I am not sure if there is an official fix out from cpanel yet on this but I have tested this even today and even had a friend test it and it works for us. It seems cpanel restart is needed in your case . Try running /usr/local/cpanel/startup after you have made the change.

I actually just opened a ticket on this very issue yesterday and was told that this can only be changed using the old stunnel implementation. Not a great solution IMO. Perhaps some day they will take PCI compliance seriously.

Code:
wget --spider --secure-protocol=SSLv2 https://hostname.com/
This should fail with an Unable to establish SSL connection message

*** To limit smtps to SSLv3 and TLS, add the following to /etc/exim.conf

Code:
tls_require_ciphers = SSLv3:TLS
And then restart exim.

You can then test with the following command:

Code:
openssl s_client -ssl2 -connect your.hostname.com:465
Try that using each of the following: -ssl2, -ssl3 and -tls1. It should now only work when using -ssl3 or -tls1. It should fail when you use -ssl2; you'll see something like this at the end and it will drop your connection:
